Because tiic want her to be some angst for poor put upon Wilson. I rather see Gabi continue to work, finish school and raise the baby etc. And Nick set up an account for her and Arianna so it's not like she's has no money.

You haven't read the spoilers, have you?

Gabi wouldn't likely return to work so soon.It appeared she was only working part time at the pub.That money would not be enough for her to pay rent on Rafe's apartment or her own,take care of the baby,and take college classes.I could also see how Will would want this arrangement too.He would be a part of his daughter's daily life not just visitation rights and still have Sonny.Gabi did not want to accept money from Nick when he first offered it,he insisted so I could see her not wanting to accept assistance from him even though she is entitled to it as his wife.
